HiFiMAN's HE400S are one of the world's most efficient planar headphones. The HE400S sound fantastic with almost any of your smartphones or portable music players. Designed to deliver superb HiFi sound, the HE400S has a comfortable and ergonomic design for long hours of listening.

The HE400S is a full-size, circumaural open-back headphone. Now sporting the new HiFiMAN headband and angled earpads that first appeared on the HE560 and HE400i, and the 2.5mm mini-jacks on the earcups that first appeared on their flagship HE1000, the HE400S a significant ergonomic improvement over the HE400.

  • Highly Efficient Planar Magnetic Headphones

    With a sensitivity of 98dB and an impedance of 22 Ohms, the HE400S can be driven very easily by any of your smartphones or portable music devices. These headphones do not require an amplifier to give the best sound they possibly can.

    Orthodynamic or Planar Magnetic Headphones

    Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. This leads to a large percentage of the diaphragm not being directly driven by those conductors. Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, the result is significantly lower distortion than conventional dynamic headphones.

    Superb Hi-Fi Quality Sound

    HE-400S is known for its enjoyable smooth mids. They have good body, good detail, enough clarity and all that with a relaxed and unfatiguing presentation. The overall balance of the HE-400S is impressive with both bass and treble fitting in nicely with the mids. Treble is on the softer side with enough clarity and detail to enjoy the music as you'd love.

    Open Back Design

    The HiFiMAN HE400s' has an open design that makes it perfect for home or studio applications. This also makes the HE400s one of the most open, dynamic and immersive sonic experience at this price point.

    Ergonomic and Comfortable Design

    The innovative faux leather headband and specially designed velour ear pads provide remarkable comfort, allowing you to enjoy your music for hours on end with no discomfort or fatigue.

    Tangle Free Detachable Cables

    The outer sheath of the detachable cables helps achieve a tangle free design that is ideal for portable players. The new 2.5mm TRS plugs also let you remove or insert the cables easily.

    Single Crystalline Silver Plated Copper Wire for Improved Connectivity 

    The Hifiman HE400s utilizes finely stranded, single crystalline silver plated copper wire for enhanced conductivity. In order to help resist interference without being bulky, the cables use a braided design and dielectric insulation.

    Replaceable Connectors

    The HE400S plugs can easily be switched and can be quickly connected to different cables and amplifiers. If you get yourself a 4 pin XLR connector, you can enjoy a fully balanced audio experience.
